Skin Changing / Stuck Buttons?

Hello there! I would like to report a skin bug on Samsung Galaxy 10 (Galaxy S10), so me and my friend was playing Minecraft with custom skins and each time I went near them my skin changed into theirs so I changed my skin to another which made their skin change into mine and it kept doing that each other we went near each other or changed our skins

Also when they kept killing me in game, my buttons got stuck. Basically frozed so I couldn't do anything but move my camera so I had to exit the game manually and it made my phone overheat badly.
